FIELD OF THE INVENTION

This invention generally relates to ornamental and utility poles, and, more particularly, to variable controlled carriages allowing for the raising, lowering, holding, locking and releasing of ornamental and utilitarian objects on poles or other elongated structures.

BACKGROUND

Utility and ornamental poles are well known in the art. Some poles are used to display signs, flags, banners, bird houses, nests, feeders and/or plants. Others are used to support communication systems, lights and security cameras. Unfortunately, such poles typically do not provide means for raising, lowering and easily removing the supported object. Thus, installation and maintenance requires the use of a ladder, crane or other personnel lifting device, which is inconvenient, costly and conducive to injury.

There is an absence of versatile carriage systems that can lift, lock in place, and lower a wide array of light, medium or heavy objects on tall elongated structures, such as poles. Specialty mast systems, as described in U.S. Pat. No. 4,429,355 to Garchinsky and U.S. Pat. No. 3,696,241 to Meyer et al. are known in the art for raising and lowering light assemblies on highway light poles. While such systems are useful for raising and lowering suspended lighting assemblies and their associated electrical wiring, such systems are not useful for plants that require irrigation. Also, when lowered, the carried assemblies are not readily removable from the mast. Furthermore, such systems typically require raising and lowering of high voltage electrical lines, which tend to wear and bind after repeated raising, lowering and long term all-weather storage, and pose serious electrocution risks. The extra wiring, which must be fed out and retracted, also adds considerably to the expense and complexity of the system.

As populations of many animal species are becoming threatened because of ecological pressures, the provision of appropriate animal houses and feeders can help support locally important populations. The environmental and aesthetic benefits of animal houses and feeders, such as nest boxes and bird feeders, including birdhouses, are well known. Animals such as birds add beauty to a yard, and along with bats, can help control pest (e.g., mosquito) populations. To be effective, such houses and feeders must be installed in a quiet place, out of the reach of predators and scavengers such as cats and raccoons, generally between about five meters above ground. Too often, people with good intentions will install a house or feeder, but then forget about it. It is important to clean out a house and feeder periodically to prevent accumulation of debris and parasite infestation. Additionally, fresh hay or wood shavings may be added to a house periodically to make the house suitable for use as a winter roost. Of course, a food must be replenished regularly in a feeder. Unfortunately, means for elevating, lowering and easily removing houses and feeders has not heretofore been provided.

As another example, pole mounted planters have been devised to beautify landscapes and architecture. Unfortunately, heretofore known pole planters cannot be easily adjusted, i.e., raised and/or lowered and rotated repeatedly, through a continuum of positions. Instead, they remain fixed at a certain elevation and angular orientation. Irrigation is equally problematic. Watering an elevated planter and caring for the plant requires use of a ladder or other tools or removal of the planter and reinstallation after the task is completed. Evenly distributing sunlight entails removal and repositioning the planter.

As yet another example, municipalities frequently displays flags and banners on sign and light posts to promote and commemorate special events and achievements. Installing, maintaining (e.g., cleaning) and removing such items requires the use of a ladder, crane or other personnel lifting device, which is inconvenient, costly and conducive to injury. When vehicles with cranes are used, they are parked alongside the pole, which contributes to traffic congestion.

What is needed is a variable controlled carriage adapted for raising, lowering, holding, locking and releasing a wide array of ornamental and utilitarian objects on poles or other elongated vertically oriented structures. The invention is directed to overcoming one or more of the problems and solving one or more of the needs as set forth above.

SUMMARY OF THE INVENTION

To solve one or more of the problems set forth above, in an exemplary implementation of the invention, a variably controlled carriages allowing for the raising, lowering, holding, locking and releasing of objects on poles or other structures is provided.

Optional features which can be included with the objects are but not limited to waterfalls, irrigation of the objects or surrounding area, or other uses of water. Objects are unlimited and not limited to such features, designs or products as planter containers, banner arms, banners, signs, (cameras, communications systems, security systems, lighting) bird and animal houses, nests and feeders. Structures are unlimited and not limited to poles of any size, shape, form, use or material, buildings, walls and/or other structures. A carriage by definition can be a wheeled vehicle, structure or support for moving, carrying or shifting another part., a heavy weight, or other objects. The carriages involved with the field of the invention are carriages that move up and down the structures as well as but not limited to fixed carriages that raise and lower objects up and down structures.

In one aspect of an exemplary embodiment of the invention, a system for raising and lowering a wide range of objects on an elongated tubular structure is disclosed. The tubular structure has a length, a base, a top opposite the base, a central channel, an inner diameter and an outer diameter. The system includes a carriage subsystem. The carriage subsystem includes a tubular body with an interior central channel an inner diameter greater than the outer diameter of the elongated tubular structure. A plurality of rollers is attached to the tubular body in the interior central channel, disposed between the tubular body and elongated tubular structure, and configured to facilitate linear translation of the tubular body along the elongated tubular structure. At least one hook is pivotally mounted on the tubular body in the interior central channel, disposed between the tubular body and elongated tubular structure, and configured to controllably engage a means for locking the carriage in a raised position. The carriage subsystem also includes a flange for attaching an object to the carriage subsystem. The flange is attached to the tubular body of the carriage subsystem. A means (e.g., a winch and cable) for controllably moving the carriage system between a lowered position adjacent to the base and a raised position adjacent to the top of the tubular structure is also provided.

In another aspect of an exemplary embodiment of the invention, a collar is attached to the top of the tubular structure. The collar includes a tubular body with an outer diameter less than the inner diameter of the tubular body of the carriage subsystem. At least one slot is formed in the tubular body of the collar and configured for engagement by the hook pivotally mounted on the tubular body in the interior central channel of the carriage subsystem. At least one pulley is rotatably mounted to the tubular body of the collar and configured for guiding a lanyard attached to the carriage subsystem at one end of the lanyard.

In another aspect of an exemplary embodiment of the invention, the system also includes a means for controllably causing the hook pivotally mounted on the tubular body in the interior central channel of the carriage subsystem to pivot towards and engage the slot formed in the tubular body of the collar and to pivot away from and disengage the slot formed in the tubular body of the collar when the hook is above the slot. A kick rod attached to the collar may be used to controllably cause the hook pivotally mounted on the tubular body in the interior central channel of the carriage subsystem to pivot towards and engage the slot formed in the tubular body of the collar when the hook is raised towards the slot. A pusher bracket with a slanted planar surface controllably causes the hook pivotally mounted on the tubular body in the interior central channel of the carriage subsystem to pivot away from and disengage the slot formed in the tubular body of the collar when the hook is above the slot. The hook may have a tip with a roller or low friction pad attached to the tip.

In another aspect of an exemplary embodiment of the invention, supported objects may include any objects suitable for support by the carriage. Such objects may include an animal house, including but not limited to a Bundt-style (i.e., having a central passage, ringed shape) animal house and a Bundt-style modular animal house. Supported objects may also include a plurality of banner arms attached to the carriage subsystem, including but not limited to a banner arm comprising an elongated coil spring. Supported objects may also include an animal feeder, including but not limited to a Bundt-style animal feeder and a Bundt-style modular animal feeder. Supported objects may also include a planter container, including but not limited to a Bundt-style planter container and a Bundt-style modular planter container.

In another aspect of an exemplary embodiment of the invention, an irrigation subsystem may be provided. An exemplary irrigation subsystem includes a water supply line extending through the elongated tubular structure and an irrigation outlet fluidly coupled to the water supply line and mounted to the collar. The irrigation outlet supplies water to a planter container. Additional irrigation such as sprinklers and microirrigation components may be included in the irrigation subsystem to controllably water planters and/or surrounding terrain.

In another aspect of an exemplary embodiment of the invention, an electrical subsystem may also be provided. A plurality of electrode assemblies may be attached to the tubular body of the collar. Each electrode assembly includes an electrically conductive contact attached to an insulating body. The plurality of electrode assemblies is configured to electrically engage similar electrode assemblies on the carriage when the carriage is raised towards the slot. Each electrode assembly attached to the carriage may be electrically coupled to an electrical load attached supported by the carriage. Electrode assemblies attached to the tubular body of the collar are electrically coupled to electric supply lines extending through the elongated tubular structure. The electrical load may be any device that requires electric power to operate, including, but not limited to a light or camera.

As U.S. Nonprovisional application Ser. No. 11/868,534, filed Oct. 8, 2007, incorporated herein by this reference, describes and depicts each of the aforementioned means for raising and lowering the carriage, for clarity and simplicity, the following description focuses primarily on a winch and pulley system. Persons skilled in the art will appreciate that the invention is not limited to a winch and pulley system. Instead, a means for controllably raising and lowering a carriage over a continuum of positions, including those means addressed above and in U.S. Nonprovisional application Ser. No. 11/868,534 may be utilized and are intended to come within the scope of the invention.

Referring to the Figures, in which like parts are indicated with the same reference numerals, various views of exemplary carriage assemblies and objects supported by exemplary carriage assemblies on poles according to principles of the invention are shown. A carriage collar attached to the top (distal) end of each pole provides pulleys for lanyards used to raise and lower a carriage, slots for engagement by locking hooks pivotally coupled to the carriage, a pusher bracket for guiding the hooks into and out of the slots, and optional electrodes for supplying electrical power to the carriage. A movable carriage supports a utilitarian and/or aesthetic object. The carriage optionally includes a flanged base to support a wide range of objects, rollers to facilitate gliding motion up and down a pole, pivoting hooks for engaging slots in the collar, and optional electrodes to make electrical contact with electrodes on the collar. Various accessories and components such as plumbing for irrigation, electrical supply lines, lanyards and a winch may be provided in the pole.

Referring now to FIG. 1, a pole structure 101 is attached to a standard Washington style lighting pole base 105 with a movable carriage 110 surrounding a portion of the pole, near the top or distal end of the pole, i.e., in the raised position 110. The pole, base or carriage can be of any style, shape, size or height and made of any material. The poles or structures may be attached or mounted to bases or direct imbedded into the ground.

Referring now to FIG. 2, the carriage 110 is shown in a lowered position resting on or near the base 105. A hand cranked winch 220 and/or an alternative electric winch 221 mounted in the base 105 control a cable 230 which in turn controls movement of the carriage up and down the structure. At the end opposite the winch, the cable 230 is attached to a yoke 232. Lanyards 234 attached to the yoke 232 are routed over a plurality of pulleys 240 and attached to the carriage 110. The pulleys 240 may be mounted on the pole, but are preferably mounted on an assembly referred to herein as a collar or collar assembly 250, which is attached to the pole, as described more fully below. The ends of the lanyards are attached to the carriage on the interior. The base 105 may be welded to the pole structure 101. A removable access panel 106 is provided to enable access to the winches for configuration and maintenance. A concrete foundation 290 may be provided to securely anchor the base 105.

The principles of the invention are not limited to a cable and winch raising and lowering mechanism. Other mechanisms for raising and lowering the carriage, such as any of the raising and lowering mechanisms described in copending U.S. Nonprovisional application Ser. No. 11/868,534, which is incorporated herein by this reference, may be utilized in lieu of or in addition to a cable and winch.

Now referring to FIG. 3, a side cut-away view of the carriage 110 and collar assembly 250 are shown. A plurality of rollers 351 spaced around the carriage 110 keep the carriage 110 from scraping against and scratching the pole 101 and facilitate smooth reduced friction travel of the carriage 110 as it is drawn up and down the pole 101. The rollers 351 may be placed in a channel 353 attached inside the carriage 110. Optionally, one or more of the rollers may be a spring biased roller 352 configured to maintain pressure against the pole 101. The spring biased roller 352 may be used when tapered pole structures are used 302. Where the tapered pole structure is smaller in diameter than the collar assembly 250, the spring urges the roller 352 against the tapered pole, keeping the carriage safely away from the pole 101. When the carriage 110 is raised, the spring roller 352 acts as a centering guide.

A plurality of irrigation pipes and/or electrical conduits 307 can be placed inside the structure. Splice joints 311, 312 connect the collar 250 and pole structure 110. The splice joints 311, 312 may also have a ring loop at the top for pipes and conduits to pass through. These splice joints 311, 312 may also be used at the top of the collar 250 to splice it to another structure, such as a continuing pole or a lighting fixture or other such system. Splice joints can optionally be solid collars or any other means suitable for joining tubular sections or a tubular section to another structure.

A catch-hook 360 allows for the carriage 110 to be raised into a locking position. The catch hook 360 is pivotally mounted to the carriage 110. Optionally, the tip of the hook may be fitted with a roller or a low friction material (e.g., a polytetrafluoroethylene pad) to facilitate ascending and descending movement and prevent scratching the finish on the pole 110. A pusher bracket 361 includes a kick rod configured to urge the hook 360 towards a corresponding slot 362 in the collar 250. Other means for urging the hook 360 forward may include a magnet positioned below the slot 362 and configured to attract another magnet on the tip of the hook 360, thereby causing the hook 360 to pivot towards the slot 362 before the slot is reached. Upon reaching the slot 362, the rising pivoted hook 360 pivots further into the slot under the influence of gravity. After the hook 360 pivots into the slot 362, the carriage 110 may be slightly lowered into a safe locking position. When locked, the hooks 360 support the weight of the carriage as well as its components, accessories and carried objects. The hooks 360 thereby relieve the cable 230, yoke 232 and lanyards 234 of substantial tension.

To unlock the carriage 110, the carriage 110 is slightly raised until a slanted plane of the pusher bracket 361 urges the hook 360, causing it to pivot gently away from the slot 362 into a released position leaning against the carriage 110. Thereupon, gravity keeps the hook 360 in the released position as the hook 360 descends with the carriage 110 below the slot 362. If the hook 360 is drawn towards the slot 362 below the slot, such as by a magnet, another means (e.g., a repelling magnet) may be provided below that point to urge the descending hook 360 back against the carriage 110. In doing so, the hook 360 will not scrape against the pole 101 as it descends.

Now referring to FIG. 4, a top view cross section of the carriage 110 and collar assembly 250 is provided. Rollers 351 are shown in channels 353 attached inside the carriage 110. Pulleys 240 are provided on the collar 250 for guiding lanyards 234. Supply lines such as irrigation pipes and/or electrical conduits 307 may extend through the pipe 101 and the collar 250.

Now referring to FIG. 5, a side cut-away view of the carriage 110 featuring a bird feeder 517 is provided. The bird feeder 517, shown in greater detail in FIGS. 6-9, is carried upon the carriage 110. In this embodiment, the collar assembly 250 extends above the carriage and feeder into the roof 515. The roof 515 and collar 250 are attached.

The system is similar to those illustrated in the exemplary embodiments described above and illustrated in FIGS. 16-18. By way of example and not limitation, the coupling means may comprise a ring frame 2910 attached to the bottom of the carriage 2515 and used to hold the planter units 2905 together. The planter lighting fixture 2510, carriage 2515 and extension 2715, and planter 2905 can be lowered for service. When lowered, the planter 2905 can be removed. The carriage 2515 travels up and down the pole 2520 for service and maintenance stopping at the base 2525. As discussed below, this embodiment includes electrical contacts and a switch disposed around the carriage 2515 and collar. The electrical contacts include a pair for the ground, power and neutral. The switch is engaged when the carriage is in the raised and locked position. The switch completes a circuit allowing electricity to flow between corresponding contacts. When the carriage is lowered, the switch is disengaged, the circuit is open and no electricity reaches the exposed contacts. The system has unlimited potential for mechanical and aesthetic variations in design and is not limited to the design or number of lighting fixtures depicted in FIGS. 29 and 30.

Now referring to FIGS. 31, 31A and 32 side views of an embodiment with a single lighting fixture 3110 are shown. The single fixture 3110 is a Bundt-style fixture that surrounds and contains the carriage. The bottom of the pole 3115 is secured in a decorative base 3120. A top cap 3105 covers the collar 3130 and seals the inner components. The collar includes pulleys for guiding lanyards 3125. As discussed below, this embodiment also includes electrical contacts and a switch disposed around the carriage and collar. The electrical contacts include a pair for the ground, power and neutral. The switch is engaged when the carriage is in the raised and locked position. The switch completes a circuit allowing electricity to flow between corresponding contacts. When the carriage is lowered, the switch is disengaged, the circuit is open and no electricity reaches the exposed contacts. The system has unlimited potential for mechanical and aesthetic variations in design and is not limited to the design or number of lighting fixtures depicted in FIGS. 31, 31A and 32. Optional locations for light sockets are 3111.

Now referring to FIGS. 33 and 34, various views of an alternative embodiment with a planter container 3340 that contains several planters 3325 are provided. The planter 3340, its contents and carriage 3370 can be lowered and raised for service using the lanyards 3305 routed over pulleys 3355 in the collar 3310. Couplings 3360 secure the lanyards 3305 to the carriage 3370. The planter container 3340 is a Bundt-style container that surrounds the pole 3350, collar 3310 and carriage 3370, and, with a bottom lip 3320, engages and rests on a flanged bottom of the carriage 3370. As described above, rollers 3335, 3345 are provided to facilitate motion of the carriage 3370. A plurality of irrigation pipes and/or electrical conduits 3375 extend through the pole 3350 and collar 3310.

A catch-hook 3315 allows for the carriage 3370 to be raised into a locking position. The catch hook 3370 is pivotally mounted to the carriage 3350. Optionally, the tip of the hook may be fitted with a roller or a low friction material (e.g., a polytetrafluoroethylene pad) to facilitate ascending and descending movement and prevent scratching the finish on the pole 3350.

A pusher bracket 3365 includes a kick rod or plane configured to urge the hook 3370 towards a corresponding slot in the collar 3310. Other means for urging the hook 3370 forward may include a magnet positioned below the slot and configured to attract another magnet on the tip of the hook 3370, thereby causing the hook 3370 to pivot towards the slot before the slot is reached.

Upon reaching the slot, the rising pivoted hook 3370 pivots further into the slot under the influence of gravity. After the hook 3370 pivots into the slot, the carriage 3350 may be slightly lowered into a safe locking position. When locked, the hooks 3370 support the weight of the carriage as well as its components, accessories and carried objects. The hooks 3370 thereby relieve the cable, yoke and lanyards 3305 of substantial tension.

To unlock the carriage 3370, the carriage 3370 is slightly raised until a slanted plane of the pusher bracket 3365 urges the hook 3315, causing it to pivot gently away from the slot into a released position leaning against the carriage 3370. Thereupon, gravity keeps the hook 3315 in the released position as the hook 3315 descends with the carriage 3370 below the slot. If the hook 3315 is drawn towards the slot below the slot, such as by a magnet, another means (e.g., a repelling magnet) may be provided below that point to urge the descending hook 3315 back against the carriage 3370. In doing so, the hook 3315 will not scrape against the pole 3350 as it descends. Optionally, a drip plate 3330 is provided to guide small volumes of water for micro-irrigation of the planters 3325.

Referring now to FIGS. 35 through 39, various views of a collar assembly 3310 and components thereof are conceptually illustrated. The collar 3310 may be mounted to a pole 3350, typically at the top of the pole 3350, using attachment tabs 3510. The collar contains components and includes features that functionally cooperate with the carriage. 3370. Among the components in the exemplary embodiment shown in FIG. 35 are pulleys 3355 for guiding lanyards, a pusher bracket 3365 for urging each catch hook pivotally mounted to the carriage into a slot 3515, electrodes 3525 for electrically connecting to corresponding electrodes mounted to the carriage when the carriage is in a raised and locked position, a switch 3520 for interrupting the supply of electricity to the electrodes 3525 when the carriage is not raised and locked into position, and guide brackets 3505 for mounting and guiding components such as utility supply lines and top structures. Roller channel guide bars 3422 align the catch-hook-release system. Rollers of the carriage 3370 travel between the guide bars 3422. The switch 3520 is a leaf spring actuated switch or a similar switch that is actuated when the carriage is raised. The electrode 3525 includes an electrically conductive contact strip 3810 and an insulating body 3805. Corresponding electrodes 3700 are mounted to the carriage 3370 in alignment with the electrodes 3525 on the collar 3310 and configured to electrically engage the electrodes 3525 on the collar 3310 when the carriage is raised and locked. The corresponding electrodes include a conductive leaf spring 3710 and an insulating body 3705. An electrical box 3802, as shown in FIG. 38, inside the collar 3310 is a junction that provides electrical power to the electrodes and an access panel 3401. If the collar is installed at some point in between the base and a lighting fixture, the splice brackets 3405 or 3410, either top or bottom, can be replaced with a solid coupling. On the top, the collar may include a dust or debris shield 3331 as well as a drip plate 3330 with a solid ring splicing collar both above and below it.

Embodiments of the invention that provide electrical circuits extending through the pole 3350 to the carriage 3370 are not limited to electrical subsystems having separable electrodes 3525, 3700. In a hard wired alternative embodiment, one or more wires pass through the pole 3350 and collar 3310 and connect to one or more outlets, jacks or electrical loads on the carriage 3370, i.e., the wires have terminals (ends or connection points) on the carriage 3370. The wires may be extendable and retractable using a spring-biased retractable roller assembly configured to let out as much wire as is needed to reach the carriage, or by containing excess wire in the pole 3350 with a weight or other biasing means configured to draw the excess wire back down into the pole 3350, or by providing rollers and pulleys operably coupled to the winch and configured to extend and retract spooled wires as the carriage 3370 is lowered or raised using the winch, or any other manner that allows an electrical coupling to be maintained between the carriage 3370 and collar 3310 as the carriage 3370 travels through its entire range of motion.

Referring now to FIGS. 40 and 41, various views of a carriage assembly 3370 and components thereof are conceptually illustrated. A plurality of channel mounted rollers 3335, 3345 spaced around the carriage 3370 keep the carriage 3370 from scraping against and scratching the pole 3350 and facilitate smooth reduced friction travel of the carriage 3370 as it is drawn up and down the pole 3350. Catch-hooks 3315 allow for the carriage 3370 to be raised into a locking position. The catch hooks 3315 are pivotally mounted to the carriage 3370. Optionally, the tip of the hook may be fitted with a roller or a low friction material (e.g., a polytetrafluoroethylene pad) to facilitate ascending and descending movement and prevent scratching the finish on the pole 3370. A flanged base 3905 is provided to support and/or attach objects to be carried by the carriage 3370. The flanged base 3905 includes tabs for engaging and/or mating with corresponding features on the objects carried by the carriage 3370. An elastomeric o-ring, gasket or seal 4105 is provided along the inner diameter of the bottom of the carriage assembly 3370 to prevent intrusion of water, debris and dust. The gasket 3370 also helps maintain alignment and prevent binding of the carriage during ascending and descending motion. Optionally, a similar o-ring, gasket or seal may also be provided near the top of the carriage 3370.

Referring now to FIGS. 42 and 43, an exemplary hook guide assembly 4200 for urging the pivotally mounted hook 4330 towards and away from a slot to lock and unlock (or release) a carriage 3370 from a collar 3310 are shown. The hook guide assembly 4200 is mounted to a collar 3310, adjacent to a slot 3515, with pin guide 4215 alongside the slot 3515 and ridge 4210 at the top of the slot 3515. The hook guide assembly 4200 is attached to the collar 3310 using a mounting bracket 4225. A furrow 4205 allows passage of the channel 4325 of the hook assembly 4300. The hook assembly 4300 is mounted on the carriage 3370 in alignment with the hook guide assembly 4200, with the hook assembly channel 4325 aligned with the furrow 4205.

The hook assembly 4300 includes a channel 4325 which is mounted to the interior surface of the carriage 3370. A hook 4330 is pivotally mounted to the channel 4325 by a pivot pin 4320. A guide pin extends laterally from the head 4305 of the hook. The head 4305 includes an inclined plane 4305 and a tip 4310. Optionally, the tip 4310 may include a roller (not shown) or a low friction pad. A notch 4335 in the channel 4325 accommodates movement of the pin 4315 during pivoting motion of the hook 4300.

The hook guide assembly 4200 includes a pin guide 4215 configured to engage and direct a pin 4315 towards a slot 3515 as the hook 4330 approaches a slot 3515 in a collar 3310. The pin guide 4215 is adjustably mounted to a shoulder 4220. Thus, the angle of the pin guide 4215 may be adjusted for optimal guidance of the pin 4315. As the carriage 3370 travels upwardly from a lowered position towards the collar 3310, the hook guide assembly 4200 mounted to the collar 3310 is stationary. As the hook assembly 4300 reaches the hook guide assembly 4200, the pin 4315 encounters the pin guide 4215, urging the pin 4315 towards the slot 3515 and thereby causing the hook 4330 to tip forward toward the slot 3515 in the collar 3310. Upon tipping forward, the hook 4330 makes an audible sound and generates a palpable impulse. Thereupon, the carriage 3370 may be lowered until the tip 4310 of the hook 4330 engages the bottom of the slot 3515. At that point, the carriage 3370 is locked and the hook 4330 carries the load of the carriage 3370.

Other means for indicating contact between the hook 4330 and slot 3515 may optionally be provided. By way of example and not limitation, a visible indicator such as a light or an audible alarm such as a buzzer may be activated when the hook 4330 pivots towards the slot 3515 a sufficient angular amount for locking engagement and/or when the hook 4330 contacts any part of the periphery of the slot 3515.

To release the hook 4330, the carriage 3370 is elevated until the inclined plane 4305 of the hook tip 4310 encounters the hook ridge 4210. The hook ridge 4210 is angled to urge the encountered inclined plane 4305 of the hook tip 4310 to pivot away from the slot 3515, back towards the channel 4325 of the hook assembly 4300. Thereupon, the carriage 3370 may be lowered without the hook engaging the slot 3515.

Now referring to FIGS. 44 and 45, alternative exemplary couplings for adjoining any separate tubular components comprising the pole, collar and fixtures are conceptually shown. For example, the couplings may be used to join the pole to the collar, the pole to a sleeve on the base, the collar to a fixture, separate pole segments 4405, 4435 to each other, or any other tubular components requiring a joint. The coupling comprises opposed notched sleeves 4415, 4430 with a center rim 4420. Notches 4410, 4425 in the sleeves 4415, 4430 allow narrowing of the diameter of the sleeves 4415, 4430 to facilitate a good fit. The center rim 4420 may extend into the interior of the coupling and comprise a disk-like flange 4420 with apertures 4500 for passage of cables, electrical wires, and pipes. Optionally, the center rim 4420 may extend outwardly beyond the outer diameter of the adjoined sections to define a flange or shelf.

Referring now to FIGS. 46 through 49, various views of an embodiment with a stationary carriage 4601 for raising and lowering lighting fixtures are conceptually shown. The carriage 4601 includes cantilever arms 4602 containing pulleys 4606 over which lanyards 4620 are routed. Lighting fixtures 4610 are suspended from the lanyards 4620 and releasably locked into a catch-hold-release system, as illustrated in FIGS. 47 through 49. The arms 4602 may hold pulley sheaths 4606 which the lanyards 4620 pass through to the yoke 232 to the cable 230 and winches.

FIG. 68 provides a high level block diagram of an exemplary photovoltaic power supply system for supplying electrical power to a pole structure and collar, in accordance with principles of the invention. In embodiments used outdoors and requiring electrical power, an optional solar power supply subsystem 6800 may be provided. As shown in FIG. 68, the solar power supply subsystem 6800 includes a photovoltaic panel (i.e., solar panel) 6805 comprising solar cells or solar photovoltaic arrays to convert light, such as sunlight, into electrical power. The solar cells may be packaged in photovoltaic modules, electrically connected in multiples as solar photovoltaic arrays, to convert sufficient energy from sunlight into electricity to meet operating requirements. As the solar cells require protection from the environment, they are packaged behind a protective transparent (e.g., glass) sheet. The solar panel 6805 preferably has an orientation and angle of inclination to take advantage of the sun's energy. In general, if the solar panel 6805 is stationary (i.e., non-tracking), in the Northern Hemisphere it should point toward true south (i.e., the orientation) and should be inclined at an angle equal to the area's latitude to absorb the maximum amount of energy year round. A different orientation and/or inclination may be used to maximize energy production in the morning or afternoon, and/or the summer or winter. The solar panel 6805 should not be shaded by nearby trees, buildings or other objects, no matter the time of day or the time of year. The solar panel 6805 may be mounted on, atop or adjacent to the planter system.

The solar panel 6805 produces direct current electricity from light, which is used to charge one or more batteries 6815. If a plurality of batteries is used, they may be connected in series and/or in parallel. A parallel combination of batteries has the same voltage as a single battery, but can supply a higher current (the sum of the currents from all the batteries). A series combination has the same current rating as a single battery but its voltage is the sum of the voltages of all the batteries.

The solar panel 6805 is preferably sized to recharge a battery 6815 within a determined amount of time, during prevailing average daytime lighting conditions. For example, one or more solar panels may be provided to deliver enough current (amps) per hour in average daylight conditions to supply enough amp hours to fully recharge the one or more batteries within a few hours or so, while the solar power supply subsystem 6800 supplies all necessary power to the planter system. The time required will depend upon the specifications and conditions of the battery or batteries, the solar panel or solar panels, and the lighting conditions. The size and/or number of batteries are preferably more than sufficient to supply power to meet operating requirements of the system throughout dusk and nighttime, and overcast days.

Although various kinds of batteries may be employed, preferably a deep-cycle battery 6815 is utilized. By way of example and not limitation, the deep-cycle battery 6815 may be a sealed or vented lead-acid battery, a nickel-cadmium battery, or some other type of deep cycle battery now known or hereafter developed. In a particular preferred embodiment the battery is an absorbed glass mat, or AGM battery, with electrolyte (acid) contained in a fine fiber Boron-Silicate glass mat that prevents spillage, even if broken, and withstands shock and vibration. Advantageously, an AGM battery also resists freezing damage, recombines oxygen and hydrogen inside the battery while charging to prevent the loss of water through electrolysis, maintains low internal resistance which avoids heating of the battery even under heavy charge and discharge currents, offer low self-discharge of approximately 1% to 68% per month.

Another component of the solar power supply subsystem 6800, a charge controller 6810, electrically coupled between the solar panel 6805 and the battery 6815, manages the electrical current supplied from the solar panel 6805 to the battery 6815 to assure maximum useful life. The charge controller 6810 does so by fully charging the battery 6815 without permitting overcharge while preventing reverse current flow at night. Circuitry in the controller 6810 reads the voltage of the battery 6815 to determine the state of charge. Based upon the detected voltage, the controller 6810 regulates the current supplied from the solar panel to the battery 6815, preferably using either Pulse Width Modulation (PWM) or Maximum Power Point Tracking (MPPT). Illustratively, a PWM controller 6810 maintains the battery 6815 at its maximum state of charge and minimizes sulfation build-up by pulsing the voltage at a high frequency. A PWM controller 6810 will first hold the voltage to a safe maximum for the battery 6815 to reach full charge. Then it will drop the voltage lower to sustain a “finish” or “trickle” charge. An MPPT controller will adjust the voltage and current supplied from the solar panel 6805 to the battery 6815, to maximize the recharging current supplied to the battery 6815. The controller also provides reverse current leakage protection by disconnecting the solar panel or using a blocking diode to prevent current loss into the solar modules at night. The controller also provides low-voltage load disconnect (LVD) to reduce damage to the battery 6815 by avoiding deep discharge. When overdischarge is detected (e.g., when a 12 volt battery 6815 drops below 11 volts), an LVD circuit will disconnect loads and reconnect the loads only when the battery 6815 voltage has substantially recovered due to recharging. A typical LVD reset point is 13 volts. In addition, the controller provides overcurrent protection with fuses, circuit breakers. Because the battery 6815 is used outdoors, the controller also provides temperature compensation, adjusting the charging voltage to the temperature. If the battery 6815 temperature differs more than a determined threshold, such as 5° C., from a reference temperature, such as 20° C., the end-of-charge voltage may corrected by a correction factor, which has the effect of increasing the end-of-charge voltage as temperature decreases.

The solar panel 6805, regardless of its size or sophistication, generates only direct current (DC). If the system requires only DC, an inverter 6820 may be unnecessary. However, an inverter is required if the image capturing system requires an alternating current (AC) load. The inverter 6820 converts DC output of the battery 6815 to standard AC power similar to that supplied by utilities. In a preferred embodiment, the inverter, if required, is a solid state electronic device that uses pulse width modulation and a low pass filter at the inverter output to produce a sine wave, quasi-sine wave or modified sine wave output waveform.

Any of the embodiments described above, particularly those that include planters, may include an irrigation subsystem with water supplied from any conventional irrigation plumbing system. Various embodiments of irrigation subsystems are described in U.S. Nonprovisional application Ser. No. 11/868,534, filed Oct. 8, 2007, and U.S. Nonprovisional application Ser. No. 12/026,553 filed Feb. 2, 2008, which are incorporated herein by this reference. As one example, with reference to FIG. 69, the pole 101 and collar 110 accommodate various irrigation components, including, but not limited to, plumbing lines, valves, controllers, joints, fittings, couplings, adapters, elbows, manifolds, microirrigation mufflers, emitters, bubblers, drippers, sprayers and sprinkler heads. By way of illustration and not limitation, a sprinkler such as a rotor sprinkler 6900 may be fluidly connected at the top of the pole 101 or collar 110 to an irrigation supply line 6915. The connection may include a coupling 6910 with a male threaded nipple 6905 configured for threaded engagement by the rotor sprinkler 6900. The sprinkler 6900 may be configured to water only one or more planter containers (not shown) on the carriage 112, only surrounding terrain 6935, or both planter containers on the carriage 112 and surrounding terrain 6935. One or more supports 6920 may be provided within the pole 101 to guide and secure the irrigation supply line 6915. At or below the base 105, the irrigation supply line 6915 connects to a coupling such as a tee or elbow 6925, which connects to a water supply line 6930.
